How I Became The World's Strongest Warrior By Using Basic Attacks Volume 4: A System Optimization LitRPG

How I Became The World's Strongest Warrior By Using Basic Attacks #4

by Kenny King

Chuck Taylor has crushed gods, broken the Tower, and solo’d nightmares that exist outside reality itself.
But numbers don’t lie, and level 58 is still 28 billion experience points away.

After helping his friends shatter their level caps and destroy the Devourer (again), Chuck sets his sights on the Dragon Lands, an untamed paradise where the monsters are stronger, the XP is massive, and the loot… doesn’t exist?

Alongside a rotating crew of overachievers, underdogs, and one mushroom with boundary issues, Chuck grinds harder than ever. Group synergy, split EXP, solo testing, optimized routes, even a DPS competition, everything is on the table in his obsessive pursuit of max efficiency.

But something strange is happening beneath the numbers.

Ancient dragons are watching. Server systems are mutating. Chuck’s becoming a legend whether he likes it or not.
And when the idea of forming a guild is floated, Chuck finds himself facing a more terrifying challenge than any boss community.

Because in the end, maybe the real grind… is friendship.
(No, seriously. The EXP boost is insane.)

This has lost a solid direction. It ends up take boring because of this. And the guild trials at the end are just silly. Don't bother setting up a situation if you are just going to ignore the rules for dramatic reasons. The ending was atrocious and cheapened the entire book.

Good read

These books are so good. Fun leveling, great empire/guild building and fantastic character relationships, both romantic and non-romantic. There have always been some intense action, however I only gave this 4 stars because of the really long angst fight at the end. It was so long I skimmed part of it. Still all and all a good book I would recommend.

Brilliant

There is no better LitRPG series out there. Chucks obsession with the numbers going up has softened a touch he now takes a little more time to look around and enjoy life more. That’s not to say he isn’t challenging himself and his friends still. He still has his toughest fights to come. It’s critical you don’t miss the next episode in this enthralling series.

Good story

I enjoyed the story and character progression. The reason I did not rate it higher was the continuity errors that made my brain hiccup and then forced me to go check and reconfirm. I won't highlight them here. If you catch them you will know, if not then enjoy the story.

Thank goodness! King returns to what he does back, efficiently leveling up the plot. He had me worried with Book 3 (so smutty, so much repetition) but this truly built on with leveling! Loved the addition of a guild tiered system and I can’t wait for where we go next! Bring on Book 5!

wow

An ending like no other or is it I’m hoping that there is a book 5. There is enough action in Kenny kings book to make you head spin in this reality or another .

Sad tears (briefly) then happy tears

Love the dynamics of the team, the fights & the quips. I can’t begin to imagine what happens next. Marvellous stuff!
